 finely pointed and apparently extremely minutely and feebl^^ ser- 

 rulate within to near the apex. Maxillary palpi very moderate in 

 size, the third joint rather slender, ovo-obconic, with the terminal 

 axial button small and obtuse, the labial palpi very minute. Men- 

 tum large, flat, polished and seulptureless, trapezoidal. Protho- 

 rax subeordate, strongly convex, feebly foveate near the base, the 

 prosternum well developed and pubescent before the coxae. Scu- 

 tellum excessively minute but present in both species, only visible 

 under high amplification. Elytra oval, strongly convex, devoid 

 of the feeblest trace of basal impression, fitted evenly and closely 

 against the broadly arcuate base of the prothorax, very narrowly 

 overlapping posteriorly, the apical truncature nearly straight and 

 anteriorly oblique sutureward, the sutural angles extremely'' mi- 

 nutely denticulate. Mesosternum very strongly carinate, the 

 middle coxae narrowly separated ; hind coxae distinctly but not 

 remotely separated, the abdominal process truncate ; first abdomi- 

 nal segment not as long as the next three, the last two rather 

 short. Legs moderate in length, the femora slightly clavate ; 

 hind tarsi much shorter than the tibiae, with the first joint not 

 quite as long as the next two ; second to fourth subequal, the fifth 

 as long as the first two, the four basal joints oblique at apex ; 

 claws extremely slender and strongly arcuate. 



The two species may be distinguished as follows : — 



Body larger, the elytra more elongate ; head broader in both sexes ; male 

 secondary characters very feeble 1 caseyi 



Body much smaller, the head narrow and subelongate in the female, broader 

 and scarcely longer than wide in the male ; secondary sexual characters at 

 the ventral apex strongly developed 2 cavifrons 



These species were both included in the description of caseiji 

 given by Dr. Brendel, cavifrons doing duty as the male and caseyi 

 as the female.

Narrowly suboval, polished and subimpunctate, pale rufo-testa- 

 ceous throughout the body, legs and antennae ; pubescence short, 

 rather sparse, evenly distributed and closely recurved, pale in 

 color but not conspicuous. Head distinctly wider than long, 

 strongly narrowed from the front to the neck, the latter scarcely 

 more than ^ of the maximum width ; sides evenly and strongly 

 arcuate ; eyes small, anterior, on the sides, very inconspicuous 

 and not convex, the facets feebly formed and wanting in the pos-
